Odoo vs SAP Business One: Which ERP Is Right for Your Australian Business in 2026?

Compare Odoo and SAP Business One for Australian businesses, including AUD pricing, Australian payroll, implementation and fit by business size.

Blog Summary

Odoo vs SAP Business One usually comes down to scope and budget. Odoo suits most Australian SMBs that want accounting, inventory, CRM, payroll and ecommerce on one platform, with Custom plan licences listed at about A$64 to A$80 per user per month. SAP Business One fits inventory-heavy or multi-entity businesses that want tighter financial controls and can carry licences of around A$213 per Professional user per month.

This comparison is for owners, finance leads and operations managers who've outgrown Xero or MYOB and have narrowed the shortlist to these two. We cover what each platform is, real AUD licence costs, Australian compliance (GST, BAS and Single Touch Payroll), implementation time and a verdict by business size. Zynex implements both, so we'll tell you where each one falls short as well as where it wins.

Introduction

The main difference is breadth versus depth. Odoo is a modular, open-core business platform that runs finance, sales, inventory, manufacturing, HR, payroll, website and ecommerce from one database. SAP Business One is an ERP built by SAP for small and mid-sized companies that concentrates on financials, purchasing, inventory, production and reporting, and relies on add-ons from SAP partners for areas such as payroll and ecommerce.

Odoo comes in two editions. Community is free and open source; Enterprise adds paid apps, hosting options and vendor support. Most Australian businesses that need payroll, full accounting and upgrades handled by the vendor end up on Enterprise. (We'll cover the edition choice in its own article, so we'll leave it there.)

SAP Business One is sold and implemented only through SAP partners. It runs on Microsoft SQL Server or SAP HANA, either on your own servers or hosted by a partner, and is typically licensed per named user with different user types for full and limited access.

If you're also weighing other options, our Odoo and Zoho comparison and our breakdown of Odoo against ERPNext cover those pairings.

Odoo wins on breadth, licence cost and how quickly you can add new departments. SAP Business One wins on financial depth, audit trails and a mature partner add-on market for distribution and manufacturing.

Licence prices change, so confirm current figures before you sign anything.

Odoo vs SAP Business One: Licence Costs and Total Budget

On licences alone, Odoo costs less for almost every Australian SMB we speak with. The bigger question is total cost of ownership: licences, hosting, implementation, add-ons, payroll and support over three years.

Here's a licence-only comparison for a 20-user business using published list prices as of October 2026 (ex GST):

Licence-only comparison (ex GST)Odoo CustomSAP Business One Professional
Monthly cost per user used in this exampleA$80A$213
Monthly cost for 20 usersA$1,600A$4,260
Annual cost for 20 usersA$19,200A$51,120
Three-year licence cost at unchanged ratesA$57,600A$153,360

Two caveats. Most SAP Business One sites mix Professional users with cheaper limited user types, which narrows the gap. And Odoo's annual billing promotions bring its figure down further. Even so, the licence gap is real.

Implementation is where the totals can flip. A lightly customised Odoo rollout is usually cheaper than a SAP Business One project of the same scope, but a heavily customised Odoo build can cost more than a standard SAP Business One rollout with proven add-ons. Typical implementation ranges:

Odoo implementation for 10 to 50 users: request a quote based on modules, migration, integrations and customisation.

SAP Business One implementation for 10 to 50 users: request a quote based on user types, add-ons, hosting and deployment scope.

Separate payroll for SAP Business One: include the payroll licence, integration and ongoing support in your estimate.

Australian Compliance: GST, BAS and Single Touch Payroll

Both handle GST. Odoo goes further for Australian payroll, because it includes STP Phase 2 reporting inside the ERP while SAP Business One sites typically pay for and integrate a separate payroll system.

Odoo's Australian accounting localisation ships with preconfigured GST taxes, a BAS report that calculates GST and PAYG withholding, TPAR reporting for contractor payments and ABA batch payment files, according to Odoo's Australian fiscal localisation documentation. One catch: the BAS report isn't lodged with the ATO directly from Odoo, so your bookkeeper still lodges through the ATO portal or a lodgement tool.

Odoo Payroll's Australian localisation is, in Odoo's words, compliant with SuperStream and Single Touch Payroll Phase 2, and it handles PAYG withholding, super and leave at termination (Odoo Australian payroll documentation). It has limits worth checking early. Odoo advises against using it for some flows, including cents-per-kilometre and travel allowances with varied withholding, and it doesn't link to the Timesheets app. Businesses with lots of casual staff or complex award interpretation should test their real pay scenarios before committing.

SAP Business One's Australian localisation covers GST tax codes and tax reporting. Confirm the available BAS reporting output with your implementation partner. Payroll is the main gap. Single Touch Payroll is the system Australian employers use to report pay information to the ATO each pay run (ATO: Single Touch Payroll), and SAP Business One customers normally meet it through a separate payroll product connected to the ERP. That's an extra licence, an extra integration and one more system for your finance team.

Implementation Timelines and What Drives Them

Odoo rollouts for SMBs are usually quicker because more departments are covered by standard apps and configuration replaces a lot of development. Across Zynex projects, our average deployment time is 6 to 12 weeks, and lightly customised Odoo projects tend to sit in that window.

SAP Business One projects of the same size typically run longer when they involve add-ons, payroll integration and multi-entity consolidation. Ask your implementation partner for a go-live estimate based on your entities, add-ons, migration and integrations.

Whichever you pick, these factors drive the timeline far more than the product:

  1. How much customisation you insist on in phase one.
  2. The state of your product, customer and supplier data.
  3. Payroll setup and at least one parallel pay run.
  4. Integrations with ecommerce, 3PL, bank feeds or EDI.
  5. Going live too close to 30 June, when finance teams are busy with end of financial year.

Which ERP Is Right for Your Business?

For most Australian businesses under 100 staff, Odoo is the better starting point. SAP Business One earns its higher cost when financial control, multi-entity reporting or a specific industry add-on matters more than breadth.

Choose Odoo If You

  • Have 10 to 100 staff and want finance, inventory, CRM, payroll and ecommerce in one place.
  • Run Shopify or WooCommerce today and want online orders to flow straight into stock and accounting, or want to move the website onto the ERP.
  • Want lower licence costs and the option to add apps department by department.
  • Have a fairly standard trading or service model without heavy intercompany activity.

Choose SAP Business One If You

  • Run several legal entities in Australia and New Zealand (or offshore) and need consolidation and intercompany controls.
  • Are a distributor or manufacturer with complex batch, serial or warehouse requirements and want a proven industry add-on.
  • Have a parent company or investors who prefer the SAP brand and audit trail.
  • Already use a dedicated payroll system you're happy with and don't need payroll in the ERP.

What Zynex Sees in ERP Selection Projects

Zynex Technologies is a Melbourne-based consultancy that implements Odoo, SAP Business One, Zoho, ERPNext and Salesforce for Australian businesses, so we don't have a reason to push one product. Here's what comes up on first calls.

The most common mistake is choosing on licence price, then customising the cheaper system until it behaves like the other one. We've seen businesses pick Odoo to save on licences, then spend that saving rebuilding a multi-entity consolidation process that SAP Business One handles out of the box. The opposite happens too: a 25-person wholesaler buys SAP Business One for the brand, then pays for separate payroll, ecommerce and CRM tools it could have had in Odoo.

The second pattern is payroll. Finance teams often forget it's in scope until week three. If you're on Xero Payroll or KeyPay today, decide early whether payroll moves into Odoo, stays where it is, or connects to SAP Business One through an integration. That decision changes the project plan.

Our rule of thumb: map your five most important processes (for example quote to cash, purchase to pay, stock receipt, month-end close and pay run), then run each one in a demo of both systems with your own data. Whichever system handles four of the five without custom code is usually the right one. If that's Odoo, our Odoo ERP development team in Australia can scope it in a short workshop.

Frequently Asked Questions

1. Which ERP is better for a 30-person Australian wholesaler?

Most 30-person wholesalers are better served by Odoo, because it covers inventory, purchasing, sales, CRM and payroll at a lower licence cost. SAP Business One becomes the better pick if you run several entities, need strict batch or serial traceability, or your parent company requires SAP. Test both with your real stock and order data before you decide.

2. Is SAP Business One worth the extra cost for a business with fewer than 50 staff?

SAP Business One is worth the extra cost under 50 staff only when you need its financial controls, multi-entity consolidation or a specific industry add-on. For a single-entity business with standard processes, the licence premium over Odoo is hard to justify. Compare three-year totals, including payroll and add-ons, rather than year-one licences.

3. Can we migrate from SAP Business One to Odoo?

Yes, you can move from SAP Business One to Odoo, but most businesses migrate open transactions, master data and opening balances rather than every historical line. Keep the old SAP database in read-only mode or export reports for audit and ATO record-keeping, since the ATO generally expects records to be kept for five years. Plan the cutover away from month-end and 30 June.

4. Does Odoo support multiple companies and consolidation?

Odoo supports multiple companies in one database with intercompany rules and separate charts of accounts, which works well for simple group structures. If you need formal consolidation with eliminations and currency translation every month, test it carefully or plan a reporting tool on top. SAP Business One is often stronger for complex group consolidation.

5. What should a 20-user business budget for ERP?

Budget for licences, implementation, data migration, training and first-year support, not just software. For a 20-user business, published licence prices alone run about A$19,200 a year for Odoo Custom and about A$51,120 for SAP Business One Professional subscriptions. Implementation is quoted separately, so ask for a fixed-scope estimate.

6. Does Australian payroll make Odoo the simpler option?

It largely does, because SAP Business One doesn't include Australian payroll out of the box and is usually connected to a separate STP-enabled payroll product. If one system for finance and payroll is a must, Odoo's Australian payroll app with STP Phase 2 is the simpler path. Check award and allowance scenarios first.
